Recipient yang terakhir tidak terima karena sender host time out.
Menurut regulasi internet mail, sender host wajib retry to send, tetapi khusus server .protection.outlook.com yang diletakkan dibelakang proxy server tidak akan menyadari bahwa sending mailnya gagal karena time out.

Jadi kalau mau recipient mau terima mail yang gagal dikirim itu harus kasih tahu ke original sender ([email protected]) untuk resend mail dengan message-ID sezpr01mb4445908304ee1e7fef668fedde...@sezpr01mb4445.apcprd01.prod.exchangelabs.com

Saran untuk server mail.mandau.id, naikkan nilai tarpit threshold atau didisable saja tarpitnya.

http://mdaemon.dutaint.co.id/mdaemon/24.0.0/security--tarpit_settings.html

SMTP RCPT tarpit threshold = 10
